EM Radiation Summary Sheets

EM Radiation Summary Sheets

Summary sheet (either one- or two-sided) for each of the seven types of electromagnetic radiation, along with a worksheet on which students can fill in information about the properties (penetration, uses and hazards) of each. I printed a couple of sets out in colour, laminated them and put them around the room for students to go and find the information.

Diffraction Discussion Questions Worksheet

Diffraction Discussion Questions Worksheet

Five questions on diffraction-related phenomena, to be used for group discussion activity. I did this with a middle-ability year 10 group, and gave four minutes for discussion. Then each group in turn read their question to the class and then gave their solution to the problem.

Reflection, Refraction and Diffraction Web Page

Reflection, Refraction and Diffraction Web Page

An interactive website suitable for use on an interactive whiteboard that demonstrates clearly in a variety of ways how waves are reflected, refracted and diffracted. Also gives some examples of uses of Reflection, Refraction and Diffraction.

Sending a Message to Alien Worlds - Research Activity

Sending a Message to Alien Worlds - Research Activity

This worksheet introduces the idea of communicating with aliens using radio signals, via the example of the ‘Arecibo message’, transmitted by very optimistic scientists in 1974. Students are asked to use the internet to find out answers to a series of questions on this topic. This could be set as a homework task, or done in class using computers. (Alternatively, written information could be provided if computers are unavailable: you can get this from various sites including www.seti.org and wikipedia.)

Refraction: Reappearing Coin Trick -Group Activity

Refraction: Reappearing Coin Trick -Group Activity

I used this as one station in a ‘Waves Circus’ to review what students had learned about waves - in this case, refraction in particular. You need to provide an opaque cup or deep bowl, and a coin or small counter. Students try out the trick and try to explain how it works in terms of light rays. This worked for quite high-level students, but some groups needed extra help and guidance.

Refraction: Disappearing Test Tube -Group Activity

Refraction: Disappearing Test Tube -Group Activity

Experiment uses glycerine and pyrex similar refractive index, so the test tube in the glycerine is almost invisible. The worksheet asks the group to examine the setup, discuss some questions and then try to think up a magic trick which makes use of this property. A good trick is to smash a test tube with a mallet, drop the shards into a glass bowl of pyrex, say the magic words and then use tongs to extract from the bowl the magically repaired test tube (which of course was there all along - just invisible). The sheet may needs adapting to give students a bit more help and guidance.

Phasors Summary (for Quantum Electrodynamics)

Phasors Summary (for Quantum Electrodynamics)

To be used as OHTs when reviewing the use of phasors in quantum electrodynamics (covered by the IOP ‘Advancing Physics’ course). There is a student handout to go with this (see under ‘Phasors Summary Handout’).

Units/quantities/ formulae revision

Units/quantities/ formulae revision

A revision exercise to look at units, quantities and formulae. Basically all you have to do is fill in the gaps - beware it is a powerpoint file, but not a presentation as such.
